Long Exposure Hotspots

I was out taking some more long exposure images last night, not the best conditions but fun anyway with some help from a friend. One thing I did do was turn off the long exposure noise reduction feature on my D700. Usually I have it on but it doubles the taken for each exposure – the normal exposure of 30 seconds say and then a second with the shutter closed for another 30 seconds. The camera then removes any hot spot noise from the image. I was in a hurry and hoped to get away without it for the images of a couple of minutes.

As it turns out it is a pain because I got a lot of hot spots and it takes time to remove them, or at least most of them. Note to self, turn the long exposure noise reduction on.

This is a 100% crop from an image, you can see the red, green and blue pixels.


This is the full image, cleaned up. 120.5s @ f/9 ISO 400





This was a 30s exposure with flash at the end, soft box and grid.




A little while ago Google bought Nik Software and today they released an update to their full collection of plugins at the fabulous price of $149 I use their plugins all the time but have also collected a few others and I was having a play this evening with Topaz Adjust 5 just for a change.  Plugins for Photoshop, Lightroom or Aperture can make processing an image much faster, giving interesting starting points and different looks, the presets provided can provide inspiration and ideas for new creative directions when processing an image. That said, I never use the presets unchanged, where is the fun in that!




Westhaven Chapel

I am shooting my first wedding in a few weeks (for a friend) and today I had a quick look around the venue. Looks pretty and unless the weather is really horrible I should manage without getting clever with flash – at least I hope so. The chapel is a simple wood lattice so light gets in all over even on a dull day which should make it easier with a fast lens and I have plenty of ISO latitude on my D700. The grounds are pretty with lots of features to play with, possibly spoilt for choice, I will have to make a few plans before the day.

Hand held HDR just to see how it might work.

Light Painting

The next task in my diploma course is to try some light painting, so I was out giving it a quick go tonight. Playing with long exposures, torches and flashes, with varying degrees of success. Using high ISO short exposures to test out composition and to get lots of stars seems to be a good place to start then take the longer exposures to add the light painting. I definitely need to play some more though.
